Abstract
This document specifies a test method for determining the minimum volume fraction of oxygen, in admixture with nitrogen, at ambient temperature, that supports combustion of small vertical sheet test specimen under a specified gas velocity that is higher than that specified in 香港六合彩开奖聽4589-2.
NOTE聽聽聽聽聽聽聽聽聽聽聽 The result is expressed as a high gas velocity oxygen index (HOI).
In addition, this document specifies the testing apparatus for determining the HOI.
The test method is applicable to materials in the form of sheets up to 2聽mm thick. It is also applicable to flexible sheet materials that are supported vertically by a specified specimen holder.
